Hi, Sam:
Great site!
I am searching a bacterial genome (40K bp) for the presence of target sites for the human miRNAs. As the max size for sequence is only 1000bps, wondering if searching <1000bps is the only way we can do? Thanks a lot! Jay

(The miRBase sequence search page is *NOT* designed to predict miRNA targets, because blast and ssearch are probably not the right tools to use for target prediction. You might prefer to use one of the bespoke target prediction tools. The miRBase search page is setup to facilitate identification of miRNA homologs.)
